266 GREEN-HOUSE INSECTS. [April. 



and after lying exposed in the shade for a few days to dry, 

 pack them up in dry moss, with their respective names 

 attached, until August, when they may be again potted. 

 Treat those that are in flower the same as directed in last 

 month. 



Dutch Roots. All the species and varieties of these that 

 have been kept in the green-house during the winter will now 

 be done flowering; the water should be withdrawn gradually 

 from them ; and then the pots turned on their sides to ripen 

 the bulbs. Or, a superior -method is, where there is the con- 

 venience of a garden, to select a bed not much exposed. 

 Turn the balls out of the pots and plant them ; the roots will 

 ripen better this way than any other. Have them correctly 

 marked, that no error may take place. They can be lifted 

 with the other garden bulbs. 



FLOWERING PLANTS 



The best situation for most plants, while in flower, is 

 where they are shaded from the sun, and fully exposed to 

 the air. Primroses, both European and Chinese, flower 

 best, and the colours are finest, where the plants are in the 

 front of the house and entirely shaded. The Chinese Azaleas 

 and Rhododendrons require, while in flower, a similar situa- 

 tion. Have all the shoots tied naturally to neat rods, and 

 keep them clear from others by elevating them on empty 

 pots, or any other substitute. See that there are no insects 

 upon them ; for they make a miserable contrast with flowers. 

 The Cdtt(\ jtEthiopica should stand in water when in bloom, 

 and even before flowering they will be much strengthened 

 by it. 



INSECTS. 



Insects will, on some plants, be very perplexing The 

 weather may admit of those that are infected to be taken 

 out of doors, and put into a frame in any way that is most 

 convenient. Fumigating them about fifteen minutes, if the 

 day is calm, will be sufficient; but if windy, they will take 

 half an hour. When done, syringe them well, and put 

 them in their respective situations. By the above method.
